Dear All, 

How calculate significant value for slope of linear trend. I could see script for finding intercept, slope and fitting a trend line; but, not it's significance value. 

Regards, 
Mahakur

Hi, Kihong -- 
The more recent versions of GrADS (2.2.*) require dynamic linking because of the switch to handling the graphics code as plug-ins. If static linking is a hard requirement, then you'll have to drop back to version 2.1.1 ( [ ftp://cola.gmu.edu/grads/2.1/ | ftp://cola.gmu.edu/grads/2.1/ ] ). My recommendations for building the supplibs for the pre-2.2 builds is at [ http://secure-web.cisco.com/1yVXfs7eixJ3hLxQ--bp_TpA1velfruUNFBKi8vFW2LvHDdP0qlP4VSLJCz_rSpE5brAR9YBE_ENXV7qR5qrPh6BV5pDRpSfNdFEM_pMMvLQcLcdwAL-38lcIp-53-8b0IE7mevBIVvWuLqvQGnK6hEH-SgZDsb0xTmOcClWexp18ZPq6huhcRuBciwUeAMh0RYGZO1kQWDn-P2yC017tpDUSTYla7qZU-JPjDC_63jhsitxrnzhcQyD20U3SCWNaSCZjhFNtGGmDEnplMhbfKEiCH2bzZ4EZ21bquLvweoHj6nVSFxiSWDvpDPk2NYX9iXpCknCDH2uc4X4B3JWd8hnBEOYzjybVD6iB2INLvQHg0FKVuEVUbbrSUQsTqLDNyhAX7B8Kt0kuEZolRZ7RAAkTwcxirFkE5m-kbQn_2ChhtfSAp2jkm58rshlIinkxCbK97y0kmdNTxCEAHea9qQ/http%3A%2F%2Fcola.gmu.edu%2Fgrads%2Fgadoc%2Fsupplibs.html |

Hi all, 

I have some questions for Installation GRADS. 
I would like to install grads static only. 

First, here is my configuration. 
### 
export CC="mpicc" 
export LDFLAGS="-L/${expat}/lib -L/${xml}/lib -L/${font}/lib -L/${szip}/lib -L/${pnetcdf}/lib -L/${curl}/lib -L/${jasper}/lib -L/${jpeg}/lib -L/${zlib}/lib -L/${gdlib}/lib -L/${tiff}/lib -L/${ftype}/lib -L/${cairo}/lib -L/${png}/lib -L/${ncurses}/lib -L/${rline}/lib -L/${gtiff}/lib -L/${gclib}/lib -L/${udunits}/lib -L/${libx11}/lib -L/${hdf5}/lib -L/${hdf4}/lib -L/${netcdf}/lib" 
export CFLAGS="-I/${expat}/include -I/${xml}/include -I/${font}/include -I/${szip}/include -I/${pnetcdf}/include -I/${curl}/include -I/${jasper}/include -I/${jpeg}/include -I/${zlib}/include -I/${gdlib}/include -I/${tiff}/include -I/${ftype}/include/freetype2 -I/${cairo}/include/cairo -I/${png}/include -I/${ncurses}/include -I/${rline}/include -I/${gtiff}/include -I/${gclib}/include -I/${udunits}/include -I/${libx11}/include -I/${hdf5}/include -I/${hdf4}/include -I/${netcdf}/include" 
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:${libx11}/lib/pkgconfig/:${cairo}/lib/pkgconfig/:${font}/lib/pkgconfig/ 
export HDF4_CFLAGS='-I/${hdf4}/include' 
export HDF4_LDFLAGS='-L/${hdf4}/lib' 
export HDF4_LIBS='-lmfhdf -ldf -ljpeg -lz -lsz' 
export HDF5_CFLAGS='-I/${hdf5}/include' 
export HDF5_LDFLAGS='-L/${hdf5}/lib' 
export HDF5_LIBS='-lhdf5 -lhdf5 -lhdf5_hl -ljpeg -lz ' 
export NC_LDFLAGS='-L/${netcdf}/lib' 
export LIBS='-lmfhdf -ldf -ljpeg -lz -lsz -lm -lcurl -lhdf5_hl -lhdf5 -lpng15 -ludunits -lnetcdf -lpnetcdf -lxml2 -ljasper -lexpat' 
./configure --prefix=$idir --enable-static --disable-shared --with-x --with-geotiff=${gtiff} --with-hdf4=${hdf4} --with-netcdf=${netcdf} --with-hdf5=${hdf5} --with-udunits=${udunits} >& configure.log 
### 

Second, my updt file is below. 
### 
gxprint GD /${grads}/lib/libgxpGD.a 
gxdisplay X11 /${grads}/lib/lib/libgxdX11.a 
gxprint gxdummy /${grads}/lib/lib/libgxdummy.a 
gxdisplay gxdummy /${grads}/lib/lib/libgxdummy.a 
gxprint Cairo /${grads}/lib/lib/libgxpCairo.a 
gxdisplay Cairo /${grads}/lib/lib/libgxdCairo.a 
### 

Finally, this is my error with running grads. 
### 
Grid Analysis and Display System (GrADS) Version 2.2.1

Landscape mode? ('n' for portrait): 
GX Package Initialization: Size = 11 8.5 
GX Package Error: dlopen failed to get a handle on gxprint plug-in named "Cairo"

GX Package Terminated 
### 

More specified. 
### 
GX Package Error: dlopen failed to get a handle on gxprint plug-in named "Cairo" 
/${grads}/libgxpCairo.a: invalid ELF header 
### 

I googled this error and found no special way to solve. 
Our system environment requires static installation, and I suspect that libcairo.a is not found in this situation. 
If you know how to resolve this kind of situation, please share your opinions. 

Thank you.
